I bought a 99 4.0 and it had been converted to coil springs and it rides horribly. I am not sure what brand of conversion it is. Any ideas as to why or what I can do? I have never had a vehicle that rides so bad. It looks like the suspension bushings are newish as well as the shocks. The vehicle was really well taken care of maintenance wise by the PO. Is it just the springs? Does anyone make a cushy spring suspension for these? I currently have newer 19" factory wheels with the factory Michelin 4x4 Synchrone tires.

Where are you located? What ride hight is your car set at with the coils. I would venture to say if your at the standard hight then tell us what shocks you have, if you are at extended hight then the shocks and springs could be a heavy duty set.. pic's please

It is at stock height and the shocks look to be factory units. Every bump is harsh. I am located in Tulsa, OK and our roads are pretty torn up. I know the 19's aren't helping but I'm not going to change them out. I am willing to try a different springs that might ride softer. Any suggestions from people with a coil conversion?

We changed ours from 18" to 19" and it really does make the ride harsher.
How much of the EAS is left on the vehicle - it might be your best option to convert back. It won't necessarily cost much more than a new set of springs.

The other thing that made for a poor ride on ours, which became even more evident after putting the 19s on, was worn upper and lower ball joints.

One of my trucks I had switched to 19's coils and my ride was harsh too. I finally bought new tires and then the ride was supper comfortable. Make sure those 19's werent sitting for years in a garage. They will harden and make the ride unbearable.

For springs I would have recomended safari guards progressive springs. But they are expensive and I believe the company might not exist anymore. So the next best would be rovertym engineering. Less expensive than safari guard. Get progressive springs all around.

On my 98 HSE I have OME 751 Heavy-Duty springs in the front and 762 Heavy-Duty in the rear (rears are progressive). I replaced the OEM shocks with ProComp ES9000 series and I am pretty happy with the way it rides. It soaks up bumps and potholes quite nicely even with the 18" wheels which definitely provie a harsher ride than a stock 16" would - which I am getting ready to switch over to. I really expected a much harsher ride with the HD springs but now the ride reminds me a lot more of the Cadillacs and Lincolns that all my polyester bellbottom wearing uncles used to drive back when I was a little kid `) . So I'm thinking your trouble is either really stiff shocks or most likley the wheel/tire combo. 19s are gonna be a lot harsher just naturally and a smaller wheel size will make a huge difference. Since that doesn't look to be an option, I agree with vmystikilv that a hardened/brittle old tire can really ruin the ride for any size tire.

Yeah surprisingly they did just bolt right in. I'll find the part numbers, the ProComp catalogue actually has an official p/n for Land Rovers. They are extended length, not by a huge amount but enough to make a big difference with the OME springs. ..my OE shocks were almost completely extended at all times. Going over speed bumps in parking lots would make the shocks go 'bang!' as they reached the end of their extension as they only had like half an inch left.

It came with 18's that rode the exact same way. It just feels like it is bottoming out the springs and bigger bumps and the little ones just jolt me all over the place. I have been thinking about putting the air bags back underneath it but I am not sure what all has been taken out. If it is just the bags and the air lines I could easily replace those but I am guessing it had some issues and that is why they took them out. If I put new shocks and springs all the way around it is going to cost about $550. I don't know if I could replace the air bags for that.

I found the parts for extended length on a Discovery, Classic, and a Defender. Which ones fit the P38?

Sorry I have been working 10 hour days and then going to class for a few hours at nite so have been posting from my phone, I'll try and find my receipt tonite and share the part number with everyone as soon as I can, In fact I think my old OE shocks are stuffed in the ProComp boxes that the replacements came in so I should be able to read the p/n right off of that. Heck I might be able to do it on my lunch hour today and post it here if go straight home.

I don't mean to threadjack so PM me if anyone wants pics etc of the setup or whatever.

Ok I ran home for lunch and I found one of the old boxes my shocks came in. p/n is 921573, which appears to the be the same as the rear shock for the Disco/Defender/RRC. The shock is loop on top, stem on the bottom and is the same for front and rear. Its not a +2" shock but has plenty of travel for my OME HD setup and doesn't overextend/run out of travel when going over harsh bumps. Hope this helps!

Yes, been looking at shocks for a while, been unsure which ones to get. DAP has monotube adventure shocks for like $62 each.
was thinking about them. Wanted a shock that would work with EAS and Coils. So all four of yours are the same then.

I considered a monotube for a minute, but part of the main point of the coil conversion was reliability and robustness (not looking to start another EAS v coil debate here, I persoanlly like both for differnt reasons) and if you dent a monotube for the most part its toast, the plunger inside won't be able to travel anymore or at least not very well. The ES9000s are pretty big in diamater compared to the OE shocks and the extra fliud volume really does help heep them from cooking the fliud inside if you have a long harsh ride and are great at resisting shock fade.
I tried to have Doetsch sell me a set of the Baja shocks but they dropped the ball bigtime and didn't really seem to want my money - they have absolutely no communication skills with their customer's whatsoever and kept strangely insisting I had a Discovery even after I gave them all the vehicle specs, mounting style and travel length etc. I was pretty bummed because their stuff seems really nice but I'm quite happy with the ProComps. I'd be willing to put them on my Disco as well once my Monroe Sensa-Turds are cashed out.
And yes all 4 corners are exactly the same. I think I paid $30-something for each one at my local 4WheelParts 'we-don't-know-what-the-hell-you're-talking-about-unless-its-a-jeep-isn't-Land-Rover-made-by-toyota?' retailer.
A made in USA lifetime warranty shock for that inexpensive just couldn't be passed up.

had the same prob with doetsch, they finally gave up and sent me a refund. Any idea if the procomps would
work with mine, I currently have EAS Not sure if they would be to long. Truck might not rest on bump stops
if eas craps out.

I had a post a short while ago but for some reason it disappeared when I hit submit.
Anyways I had said that I will measure the compressed length of the OE shock when I get a chance and we can compare it to the specs of the ProComp 921573. I seem to recall that its compressed length was only slightly longer than the OE unit.
